Motor is trembling when i accelerate - RAV4 Toyota Cars & Trucks

indicates failed wheel bearing , no disc pads or damaged disc rotor
Take it to an accredited professional brake shop for a proper diagnosis

Possible broken motor mount or torque strut. Your engine is probably rocking too far when it is put into gear. The torque strut will prevent that. The rubber bushing n the strut is probably bad.

tune up , new plugs and wires

It sounds like you have overfilled the crankcase, recheck the level.

From what I have seen, a tremble is usally an out of balance condition. Check you blades and see if you can see one of the fan blades that has been damaged. Eventually, it will affect the fan motor but it will take some time.

If you take it to autozone or one of those type places they can identify the problem with a code. Then you can go from there.

i would recomend checking your motor mounts they might be bad if not change oil with oil filter , sprark plugs along with your coils if needed, air filter and haveing your injectors cleaned just basicly a good tune up should do the job.

First-NEVER add anything to an automatic trans.
Your vehicle should use Mercon V --PERIOD
Change it at least three times, to get the Lucas out.

Have the TPS Sensor checked out.
You most likely have a Tran Pack Solenoid going bad.
It is bolted to the valve body. You can do it yourself

should have bought american!!!!!!!

wiggling or trembling are mostly cause by the front wheels.
it could only be unbalanced air pressure of the tires.
if not, it could be loose tie rod ends connecting to the steering wheel. fittings might have been worn out already and needs to be replaced.
to check whether if which side is causing it, lift or jack the left or right tire, then manually try to wiggle it, push or pull it, try every possible way to determine and looseness on the wheel. do the same on the other front wheel.
if one of then is loose or wiggles as you check, then there is a loose part on that wheel. check carefully.
